Abstract

This paper presents an image sensor SOC consisting of a 64 × 48 array of logarithmic energy harvesting pixels and associated readout circuits. The pixel array can be configured to harvest energy during idle mode and store energy in an off-chip battery or super capacitor, which offers the potential for self-powered operation where the system can be run with energy harvested solely from the chip. Measurement results from the image sensor node show peak harvested power of 5.8 μ W, which equates to the system being able to process a frame every 1.3 seconds (or 25.3 seconds if transmitter is considered as well) when operated solely from harvested energy. The sensor is also able to switch into harvesting mode autonomously whenever a frame has finished processing, thus demonstrating the feasibility of autonomous self-powered operation.
